TheApple A12 Bionic is a64-bitARM-basedsystem on a chip (SoC) designed byApple Inc., part of theApple silicon series,[8] It first appeared in theiPhone XS and XS Max,iPhone XR,iPad Air (3rd generation),iPad Mini (5th generation),iPad (8th generation) andApple TV 4K (2nd generation).[8][5] Apple states that the two high-performance cores are 15% faster and 40% more energy-efficient than theApple A11's, and the four high-efficiency cores use 50% less power than the A11's.[8][7] It is the first mass-market system on a chip to be built using the 7 nm process.[9]
The Apple A12 SoC features an Apple-designed 64-bitARMv8.3-A six-core CPU, with two high-performance cores calledVortex, running at 2.49 GHz, and four energy-efficient cores calledTempest.[4][5] The Vortex cores are a 7-wide decodeout-of-ordersuperscalar design, while the Tempest cores are a 3-wide decode out-of-order superscalar design. Like the A11's Mistral cores, the Tempest cores are based on Apple's Swift cores from theApple A6.[10]
The A12 also integrates an Apple-designed four-coregraphics processing unit (GPU) with 50% faster graphics performance than the A11.[4][8] The A12 includesdedicated neural network hardware that Apple calls a "Next-generation Neural Engine."[11] This neural network hardware has eight cores[7] and can perform up to 5 trillion 8-bit operations per second.[4][5] Unlike the A11's Neural Engine, third-party apps can access the A12's Neural Engine.[12]
The A12 is manufactured byTSMC[1] using a7 nm[5]FinFET process, the first to ship in a consumer product,[4][1] containing 6.9 billion transistors.[1] The die size of the A12 is 83.27 mm2, 5% smaller than the A11.[13] It is manufactured in apackage on package (PoP) together with 4GiB ofLPDDR4X memory in the iPhone XS[2] and XS Max[13] and 3 GB of LPDDR4X memory in the iPhone XR, the iPad Air (2019), the 5th generation iPad mini, and the iPad (2020).[14] The ARMv8.3 instruction set it supports brings a significant security improvement in the form of pointer authentication, which mitigates exploitation techniques such as those involving memory corruption, Jump-Oriented-Programming, andReturn-Oriented-Programming.[15]
The A12 has video codec encoding support forHEVC andH.264. It has decoding support for HEVC, H.264,MPEG‑4 Part 2, andMotion JPEG.[16]
